After a year-and-a-half-long layoff due to stalled contact negotiations, Strikeforce women’s featherweight champion Cristiane “Cyborg” needed little time to make short work of overmatched opponent Hiroko Yamanaka.

The bout co-headlined the Showtime-televised main card of “Strikeforce: Melendez vs. Masvidal,” which took place at Valley View Casino Center in San Diego.

Santos, who closed as an approximate -1450 (94 percent) favorite, proved the oddsmakers correct with a blitzkrieg of offense. She quickly dropped Yamanaka with a right hand and then followed her to the mat with additional punches. Santos then briefly considered a rear-naked choke before giving it up and allowing Yamanaka to stand. But with her opponent pinned against the fencing, Santos unloaded more punches and dropped to her to force a merciful stoppage.

The abbreviated performance earned Santos her quickest win to date.

“I’m very happy,” Santos said. “I trained very hard. This is amazing. I love fighting. I want to fight more.”

Santos said she’d like to remain at 145 pounds, though officials have struggled to find suitable opponents. They could come at 135 pounds, which is a much deeper division. However, when it comes to the outspoken and fast-rising Ronda Rousey, Santos doesn’t care where that fight happens.

Santos (11-1 MMA, 5-0 SF) has now won 11 straight fights, and all of the Strikeforce victories have ended in knockouts. Yamanaka (12-2 MMA, 0-1 SF), a JEWELS vet who made her Strikeforce debut, snaps an eight-fight win streak.

UFC women’s bantamweight champion Ronda Rousey is probably the greatest female fighter on the planet, which is a tremendous feat. So why are we seemingly so obsessed with arguing about whether she could beat up men?
